(Round your answer to one decimal place.) (o) Find the probability that during the year, a U.S. resident was male and between 20 and 44 years of age, inclusive. (Round your answer to one decimal place.)Explanation / Answer
a) We are to find the probability that during hte year, a U.S. resident was female;
Probability of a resident being a female = number of females / total number of residents
= 154133/ (154133 + 149928) =154133/ 304061 = 0.506914;
Thus, probability of a resident being a female = 0.506914
b) Probability that during the year a US resident was male and between 20 and 44 years (inclusive) of age
= number of males between 20 and 44 / total number of residents
= 53,092 / 304061 = 0.174609;
Thus, probability of a US resident being a male and between 20 and 44 years = 0.174609;
